During recent INTEGRAL observations of the Galactic Center field (PI Sunyaev) we detected the positive hard X-ray flux from the X-ray nova and black hole candidate GRS 1739-278. The source was first discovered with Granat/SIGMA during its intense outburst in 1996 (Vargas et al., 1997, Borozdin et al., 1998). The previous known outburst of the source was observed by Swift-BAT (ATel #5986) and INTEGRAL (ATel #5991) in 2014.

According to our analysis of the current IBIS/ISGRI data, the 20-60 keV flux from the source raised from 15.4(+-1.4) to 30(+-1.4) mCrab between September 7 and 18, 2016. This may indicate the beginning of the new outburst of GRS 1739-278. INTEGRAL will continue monitoring of this region.
